Is it really unnecessary?  The reason why it is resized is
that Emacs detects that the message doesn't fit in the
height of the normal line.  Perhaps, you font has
unnecessarily big ascent or descent value.

Yes, because redisplay happens only after the execution of
the above code is finished.

I have no idea.

By they way, even with the default value of
resize-mini-windows (grow-only), the behaviour of quail
input method should be improved.  Previously, it resizes the
echo area so frequently, but now it makes the area taller
just once, and keep that hight until you turns the input
method off.  Could you verify it?
